The invention belongs to the technical field of helicopter emergency floating systems, and discloses a buoy of an anti-overturning drawstring type helicopter emergency floating system, and the buoy isarranged below a cockpit door of a front fuselage; the buoy comprises a main bag, an auxiliary bag, an anti-overturning front pull belt, an anti-overturning rear pull belt, a front upper pull belt, arear upper pull belt, a front lower pull belt, a rear lower pull belt and a front pull belt. The main bag and the auxiliary bag are connected in an embedded structure. The overturn-preventing front drawstring and the overturn-preventing rear drawstring are positioned at the uppermost end of the buoy; the front upper pull belt, the rear upper pull belt, the front lower pull belt, the rear lower pull belt and the front pull belt are positioned on the inner side of the auxiliary bag; the overturn-preventing front pull belt, the overturn-preventing rear pull belt, the front upper pull belt, the rear upper pull belt, the front lower pull belt, the rear lower pull belt and the front pull belt are connected to the fuselage structure. Enough buoyancy is provided to ensure that the helicopter hasenough lateral restoring moment, and lateral overturning of the helicopter is prevented.
本发明属于直升机应急漂浮系统技术领域,公开了一种防倾覆拉带式直升机应急漂浮系统的浮筒,浮筒布置在前机身驾驶舱门下方;所述浮筒包括:主囊、副囊、防倾覆前拉带、防倾覆后拉带、前上拉带、后上拉带、前下拉带、后下拉带和前拉带;主囊和副囊的连接形式为相嵌式结构;防倾覆前拉带和防倾覆后拉带位于浮筒最上端;前上拉带、后上拉带、前下拉带、后下拉带和前拉带位于副囊内侧;防倾覆前拉带、防倾覆后拉带、前上拉带、后上拉带、前下拉带、后下拉带和前拉带分别连接到机身结构上;提供足够的浮力保证直升机有足够的侧向恢复力矩,防止直升机侧向倾覆。
